I would also be interested in the answer to this question.
We have a new combi boiler and our old shower is now unusable, as the pressure is so high it's actually painful [feels like jabbing you in the face with needles!] and it's very difficult to regulate the heat because a] the dial is too hard to turn because of the pressure [and being old] and b] we have the same hit and miss, a whisker either way water temperature situation as wilco69.
There seems to be one optimum flow speed for the hot water in all taps, a tad under and it's cold and a tad over, it also starts to run colder because the water is apparently travelling through the combi too fast to warm up properly. It's quite tricky to hit just the right speed, but I guess that will come with practice
We will be fitting a new bathroom suite shortly, and I'd really be grateful if someone could advise us as to what type, and possibly make of shower to select. We have a separate shower cubicle, and the boiler is a Ravenheat combi [non modulating] and we no longer have hot and cold water tanks. Our mains water pressure seems to be very good.
Also any special advice on taps to select for bath and washbasin.
Many, many thanks in advance for any advice and suggestions.
